Vehicle Safety System and Operating Method Thereof

1. A vehicle safety system, comprising: a sensing unit configured to capture an image frame containing an eyeball image of an eyeball from a predetermined distance; a processing unit configured to calculate an eyeball position in the image frame, and generate a drive signal corresponding to one of at least two sub-regions in the image frame in which the eyeball position locates; and a control unit configured to trigger a vehicle device associated with the one of the at least two sub-regions in which the eyeball position locates according to the drive signal, and stop controlling the vehicle device according to the drive signal when the eyeball position locates in a no control sub-region in the image frame.

2. The vehicle safety system as claimed in claim 1 , wherein the sensing unit is configured to transmit the image frame to the processing unit in a wired or wireless manner.

3. The vehicle safety system as claimed in claim 1 , wherein each of the at least two sub-regions corresponds to one of different functions, and each of the different functions is configured to control one vehicle device including a vehicle navigation device, a side view camera and a rear view camera.

4. The vehicle safety system as claimed in claim 1 , further comprising a display unit configured to show information of the vehicle device.

5. The vehicle safety system as claimed in claim 1 , wherein the processing unit is configured to generate the drive signal when identifying the eyeball position is at the one of the at least two sub-regions for a predetermined time interval.

6. The vehicle safety system as claimed in claim 1 , wherein the processing unit is further configured to identify blinks according to a plurality of image frames outputted by the sensing unit, and generate the drive signal when identifying the eyeball position is at the one of the at least two sub-regions with a predetermined number of blinks.

7. The vehicle safety system as claimed in claim 1 , wherein the sensing unit is disposed on eyeglasses, a headwear accessory or a portable device.

8. An operating method of a vehicle safety system, the operating method comprising: capturing an image frame containing an eyeball image of an eyeball; calculating, by a processing unit, an eyeball position of the eyeball image in the image frame; generating a drive signal corresponding to one of at least two sub-regions in the image frame in which the eyeball position locates; triggering a vehicle device associated with the one of the at least two sub-regions in which the eyeball position locates according to the drive signal; and stop controlling the vehicle device according to the drive signal when the eyeball position locates in a no control sub-region in the image frame.

9. The operating method as claimed in claim 8 , further comprising: generating the drive signal when identifying the eyeball position is at the one of the at least two sub-regions with a predetermined number of blinks.

10. The operating method as claimed in claim 8 , further comprising: generating the drive signal when identifying the eyeball position is at the one of the at least two sub-regions for a predetermined time interval.

11. The operating method as claimed in claim 8 , further comprising: showing, by a display unit, information of the vehicle device.

12. The operating method as claimed in claim 8 , further comprising: identifying a pupil image and at least one glint image in the image frame; and calculating a relative distance between the pupil image and the at least one glint image to track the eyeball.

13. A vehicle safety system, comprising: a sensing unit configured to capture an image frame containing an eyeball image of an eyeball; a processing unit configured to generate a drive signal corresponding to one of at least two sub-regions in the image frame in which the eyeball image is located; and a control unit configured to trigger a vehicle device associated with the one of the at least two sub-regions in which the eyeball image is located according to the drive signal and stop controlling the vehicle device according to the drive signal when the eyeball position locates in a no control sub-region in the image frame.

14. The vehicle safety system as claimed in claim 13 , wherein the processing unit is configured to generate the drive signal when identifying the eyeball position is at the one of the at least two sub-regions for a predetermined number of image frames.

15. The vehicle safety system as claimed in claim 13 , wherein the processing unit is further configured to identify blinks according to a plurality of image frames outputted by the sensing unit, and generate the drive signal when identifying the eyeball position is at the one of the at least two sub-regions with a predetermined number of blinks.

16. The vehicle safety system as claimed in claim 13 , wherein each of the at least two sub-regions corresponds to one of different functions, and each of the different functions is configured to control one vehicle device including a vehicle navigation device, a side view camera and a rear view camera.

17. The vehicle safety system as claimed in claim 13 , further comprising a display unit configured to show information of the vehicle device.
